Description

Technical Field

[0001] The invention relates to the technical field of explosion-proof materials, and more specifically to a spherical barrier explosion-proof filling body structure. Background Art

[0002] During the storage, transportation, delivery and use of flammable and explosive fluids such as various gasoline and diesel, alcohol fuels, liquefied gas, natural gas and hazardous chemicals, their storage and transportation containers or pipelines are very prone to explosion hazards. In recent years, the upgrading and development of diversified explosion-proof technologies have effectively solved the safety issues of flammable and explosive liquids (gases) during production, storage and transportation.

[0003] Among them, spherical non-metallic barrier explosion-proof technology is a new generation of intrinsically safe technology with significant flame retardant and explosion suppression effects. Its typical representative product is a non-metallic barrier explosion-proof material with a thin-walled hollow spherical structure, usually composed of multiple thin-walled rings, sheets and other structural features interlaced along the longitude and latitude. It is a polymer material mainly prepared by mixing a variety of non-metallic substrates, flame retardant materials, antistatic materials, and various additives.

[0004] There are two types of spherical non-metallic barrier explosion-proof bodies on the market. One is that there are more void areas, the medium has better fluidity, but the barrier property is low. The other is that the void area is smaller, the barrier property is good, but the medium has poor fluidity, which affects the transportation, filling, and removal of liquid and gas media.

[0005] During the application process, it was found that the more common hollow spheres on the market are composed of a single ring-shaped structure, which is difficult to balance key performance indicators such as barrier and explosion-proof performance, filling performance, structural strength, and medium fluidity. It is difficult to take into account all the key performance indicators. In particular, some products are overly simplified in design to meet the filling performance, resulting in insufficient structural strength, easy breakage during use, shortened service life, and limited practicality and application scope.

[0006] In addition, most of the spherical barrier explosion-proof materials on the market are made by injection molding. The structural design needs to take into account the processability and mass production scale of the injection molding process. Some structural designs are too complicated and difficult to achieve mass production, and the mold cost and production cost are high; some structural designs are too simple, resulting in low structural strength, poor filling performance, and even affecting the explosion-proof performance.

[0007] Based on this, we provide a spherical barrier explosion-proof filling body structure. Summary of the invention

[0030] The following is combined with Figures 1 to 6 The present invention is described in further detail.

[0031] It should be noted that the drawings are schematic and not to scale. For the sake of clarity and convenience, the relative sizes and proportions of the parts shown in the drawings are exaggerated or reduced in size, and any size is only illustrative and not restrictive. In addition, the same reference symbol is used for the same structure, element or accessory appearing in more than two figures to reflect similar features.

[0032] Embodiment 1

[0033] The embodiment of the present invention discloses a spherical barrier explosion-proof filling body structure. Figures 1 to 4 A spherical barrier explosion-proof filling body structure, comprising an equatorial portion 1, a southern hemisphere portion 2 and a northern hemisphere portion 3, and also comprising a plurality of barrier tiles 1 4 and barrier tiles 2 5; each barrier tile 1 4 is arranged at the periphery of the equatorial portion 1, and one end of the barrier tile 1 4 is connected to the southern hemisphere portion 2, and the other end of the barrier tile 1 4 is connected to the northern hemisphere portion 3; each barrier tile 2 5 is arranged at the periphery of the equatorial portion 1, and one end of the barrier tile 2 5 is connected to the southern hemisphere portion 2, and the other end of the barrier tile 2 5 is connected to the northern hemisphere portion 3; the barrier tiles 1 4 and the barrier tiles 2 5 are arranged in a circular array and are integrally connected to the equatorial portion 1;

[0034] At the transitional connection between structures, which is a relatively weak link, the structural strength can be improved by adding reinforcing columns 8 in a conical, cylindrical or other shape;

[0035] Special note: Under the premise of ensuring sufficient structural strength, it is more conducive to improving the molding efficiency of injection molding. The length of the reinforcing column 8 can be adjusted according to the need for strength improvement, and the longest length can run through the entire sphere.

[0036] A circular array structure consisting of multiple semi-enclosed groove-shaped "reverse-bow barrier tiles" is distributed on the equatorial part 1; the latitude rings of the northern and southern hemispheres are connected by a circular array structure of "reverse-bow barrier tiles"; the north and south poles are designed with polygonal or circular ring or column ring structures, and connecting bridges and reinforcing column 8 structures are designed between different characteristic components, thereby further enhancing the overall structural strength, specific surface area and barrier performance.

[0037] It is worth noting that the "reverse-bow barrier tile" is a series of protective shield-like structures arranged in a circular array. It has a concave reflective surface feature on the front and a supporting structure feature on the back. It can effectively slow down, block or eliminate the propagation of shock wave energy or flames caused by explosions, high temperatures, impacts and combustion. This structure can effectively increase the sphere's lateral resistance to explosion impact and suppression of flame propagation, thereby enhancing the barrier and explosion-proof performance of the entire structure.

[0038] At the same time, the "reverse-bow barrier tile" structure is applicable to all spherical structures on the market with equatorial rings and latitudinal ring structures, regardless of whether there is a reinforcing rib structure on the equatorial ring.

[0039] Specifically, the opening of the barrier tile 4 is opened outwardly toward the outside of the equatorial portion 1, and the two side edges of the opening are arranged away from each other.

[0040] Specifically, the barrier tile 4 includes a U-shaped plate 1 400, a U-shaped plate 2 401 and a connecting plate 402. The U-shaped plate 1 400 is vertically fixed to the U-shaped plate 2 401, and the U-shaped plate 1 400 and the U-shaped plate 2 401 are staggered. The connecting plate 402 is fixed to the sides of the U-shaped plate 1 400 and the U-shaped plate 2 401, and an opening is provided at the connection between the U-shaped plate 1 400 and the U-shaped plate 2 401.

[0041] Furthermore, the middle portion of the barrier tile 4 has a "staggered layer" structural design and an "open hole" feature to balance the barrier properties and flow properties of the structure.

[0042] Specifically, one end of each connecting plate 402 is fixed together, and a reinforcing plate (403) is provided between the side ends of the connecting plates 402; the other end of each connecting plate 402 is fixed together through a connecting portion 404.

[0043] like Figure 1 and Figure 2 A group of barrier tiles 4 reflecting surfaces are directed outward from the center of the circle, and the optimized layout design is: connected integrally with the equatorial portion 1 and arranged along the circumference of the equatorial ring or the latitude ring.

[0044] Specifically, the barrier tile 2 5 includes an arc plate 500 and a connecting plate 501, one end of the connecting plate 501 is fixedly connected, and the other end of the connecting plate 501 is fixedly connected; one end of each connecting plate 501 is connected to form a southern hemisphere part 2; the other end of each connecting plate 501 is connected to form a northern hemisphere part 3.

[0045] like Figure 1 and Figure 2 The barrier tile group 25 is inward along the center of the circle, and the optimized layout design is: it is integrated with the north and south latitude rings, passes through the sphere, and is arranged along the circumference of the latitude ring or the equatorial ring.

[0046] Specifically, each connecting plate 501 forms a closed shape after being connected, and the outer side surface of the closed shape is designed as a through opening.

[0047] It is worth noting that: Figure 3 and Figure 4 As shown, the shape of the "reverse bow-type" barrier tile can be designed in a variety of open shapes, and can be a semi-enclosed open "groove" structure of other different shapes.

[0048] Specifically, the northern hemisphere portion 3 further includes a connection panel 502 , and the connection panel 502 is connected to the connection portion 404 .

[0049] It is worth noting that the projected cross-sectional area (i.e. wind resistance or drag area) and the void area ratio of the main viewing angle of the present invention are better than those of most similar products on the market, and therefore have better "barrier" performance.

[0050] At the same time, under the premise of ensuring good processability, the entire structure is staggered and the layout is ingenious and reasonable, so that the structure has both good barrier and explosion-proof effects and good medium fluidity. When liquid and gaseous media flow, the resistance to passing through is small, and there is no obvious blocking effect on the flow rate. There is no obvious effect on the transportation, filling, and removal of liquid and gaseous media.

[0051] Specifically, a barrier plate 6 is fixedly connected to the side of the equatorial portion 1 and between the barrier tile 1 4 and the barrier tile 2 5. By providing the barrier plate 6, the projected cross-sectional area along the center axis of the sphere (i.e., the wind resistance or resistance area) is further increased, which can effectively increase the explosion impact resistance in the direction of the symmetry axis of the sphere, inhibit flame propagation, and the overall flame retardant and explosion-proof performance.

[0052] The number of barrier tiles 1 4 and barrier tiles 2 5 can be one, two, three, four, five, six, seven, eight, etc., arranged in a ring array.

[0053] It is worth noting that the "convex" barrier sheet 6 can be in a semicircular arc shape, or in other regular or irregular "convex" shapes. The number is not limited to the number shown in the figure, and can be one, two, three, four, five, and so on.

[0054] Specifically, a reinforcing rib 7 is fixedly connected to the side of the equatorial portion 1 and located between the barrier tile 1 4 and the barrier tile 2 5 , and one side of the reinforcing rib 7 is connected to the barrier tile 1 4 , and the other side is connected to the barrier tile 2 5 .

[0055] Specifically, the equatorial part 1, the southern hemisphere part 2 and the northern hemisphere part 3 are all suitable for injection molding technology, and can also be produced by 3D printing.

[0056] Embodiment 2

[0057] The embodiment of the present invention discloses a spherical barrier explosion-proof filling body structure. Figure 5 and Figure 6 As shown, a spherical barrier explosion-proof filling body structure includes an equatorial portion 1, a southern hemisphere portion 2 and a northern hemisphere portion 3. In this embodiment, the cylinder formed by the southern hemisphere portion 2 and the northern hemisphere portion 3 is a cylindrical, annular or other cylindrical structure. By designing it to be cylindrical, the overall load-bearing capacity is made stronger.

[0058] From the above content, it can be seen that the present invention has comprehensively optimized and improved the barrier and explosion-proof performance, loading and filling performance, overall structural strength, and injection molding processability of the spherical explosion-proof material. The present invention has good barrier and explosion-proof performance, medium flow performance, loading and filling performance, structural strength, and also has good injection molding processability, and is suitable for large-scale mass production.
